Road and infrastructure projects place some of the most demanding requirements on survey teams: long corridors, live traffic environments, tight vertical tolerances for drainage, and coordination with RTA and utility authorities throughout.
Survey Stages on a Road Project
- Corridor topographic survey — existing ground, utilities, structures and features along the full alignment
- Control network establishment — GNSS primary control with total station densification along the corridor
- Alignment setting out — centrelines, kerb lines, drainage inverts and structure positions
- Layer-by-layer level verification — subgrade, road base and asphalt levels against design tolerances
- As-built survey — final documentation for authority handover
Working in Live Traffic Environments
Surveying alongside live traffic requires RTA-compliant traffic management, appropriate permits and careful method planning. Night works are common for lane-closure-dependent measurements on operational roads.
Drainage: Where Vertical Accuracy Rules
Stormwater drainage designs in Dubai often run at very shallow gradients, meaning invert level tolerances are tight. Setting out and verification of drainage inverts is typically the most accuracy-critical survey task on a road project — millimetres matter.
Frequently Asked Questions
Do you handle RTA submission formats?
Yes — deliverables for road projects are prepared in the formats required for RTA review and handover documentation.
Can drone survey be used for corridor mapping?
Yes, for the topographic stage — drone mapping is highly effective for corridor surveys, with ground survey supplementing areas obscured by traffic or trees, and all construction setting out done by ground methods.
